Abstract:: Taking Syringa reticulata ssp.amurensisseed as tset material,the effect of different concentrations of GA₃,different soaking time，different temperature，different light condition on germination of seeds were studied,in order toscreen suitable condition of breaking dormancy and seeds germination.The results showed that GA₃treatment could quickly break seed dormancy and promoted seed germination,there were significant differences on concentration of GA₃ and soaking time of seed germination(P<0.05).Germination rate,germination energy，soluble sugar content and soluble protein content of seeds achieved the highest at 200 mg/L GA₃ soaking seeds for 24 h.Under the variable temperature of 20℃/25℃（12 h/12 h）and illumiration of 12 h/12 h(light/dark) achived the best germination effect.
